Mandevilla plant named ‘Sunparaprero’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Sunparaprero’, characterized by its upright and vining plant habit; relatively small glossy foliage; freely flowering habit; dark pink-colored flowers; and long flowering period.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘Sunparaprero’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunparaprero’.

The new Mandevilla is a product of a planned breeding program conducted by the Inventors in Yokaichi-shi, Shiga, Japan. The objective of the breeding program is to create new Mandevilla cultivars with large and uniquely colored flowers.

The new Mandevilla originated from a cross-pollination made by the Inventors in Yokaichi-shi, Shiga, Japan in February, 2002, of a proprietary selection of Mandevilla hybrida identified as code number M35-4, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number M28-3, not patented, as the male, or pollen, parent. The cultivar Sunparaprero was discovered and selected by the Inventors as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Yokaichi-shi, Shiga, Japan.

Asexual reproduction of the new cultivar by cuttings in Yokaichi-shi, Shiga, Japan, since October, 2003, has shown that the unique features of this new Mandevilla are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sunparaprero have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunparaprero’. These characteristics in combination distinguish ‘Sunparaprero’ as a new and distinct cultivar:

-   -   1. Upright and vining plant habit.     -   2. Relatively small glossy foliage.     -   3. Freely flowering habit.     -   4. Dark pink-colored flowers.     -   5. Long flowering period.

Plants of the new Mandevilla differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have red-colored flowers. In addition, leaves of plants of the new Mandevilla are narrower than leaves of plants of the female parent selection.

Plants of the new Mandevilla differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have pale pink-colored flowers.

Plants of the new Mandevilla can also be compared to plants of the Mandevilla cultivar Sunmandecos, disclosed in U.S. Plant Pat. No. 15,202. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of the cultivar Sunmandecos in the following characteristics:

-   -   1. Plants of the new Mandevilla had shorter and finer lateral         branches than plants of the cultivar Sunmandecos.     -   2. Plants of the new Mandevilla had shorter, glossier and darker         green-colored leaves than plants of the cultivar Sunmandecos.     -   3. Plants of the new Mandevilla had smaller flowers than plants         of the cultivar Sunmandecos.
